Although no significant changes in total plasma IgG or IgA levels were observed in the RV group compared to CON, infection with RV increased the Th1/Th2 ratio (p < 0.05), estimated from the concentration of the different IgG subtypes (IgG2b + IgG2c/IgG1 + IgG2a) (Figure 2B,C). The gene discussed is CD79A; the disease is infection.
